Wanting to save Seira and Luna, Akari agrees to Cerebrum's conditions and is transported to a place called the Sephirothic Tree, where he intends to use a device called the Clessidra so that they can mate, returning Seira and Luna to normal in exchange. Inside the Clessidra, Cerebrum forces Akari to relive the day Fuyuna died,hearing her thoughts of hatred towards her over and over, until she loses enough of herself to be his. Arriving at the Sephirothic Tree, Seira and Luna face up against an army of tree Daemonia, which they manage to defeat thanks to the mysterious arrival of Ginka. Meanwhile, Akari, believing that Fuyuna became a Daemonia because of her, is hanging on to the last of her sanity.
